Protein Structure

UniProt Annotation

Function

Protease-inhibitor that contains multiple distinct protease inhibitor domains. Probably has serine protease- and metalloprotease-inhibitor activity (By similarity). Inhibits the biological activity of mature myostatin, but not activin. {ECO:0000250}.

Subcellular Localization

Secreted {ECO:0000269PubMed:12595574}.

Disease Associations

Tissue Specificity

Widely expressed, with high expression in skeletal muscle and heart. Also expressed in brain, lung and testis. Weakly expressed in liver and kidney. {ECO:0000269PubMed:12595574}.
